Not quite, I'm afraid. Even if the disk isn't spinning, we still have to

make sure that it won't spin up in a precarious situation. Of course, if

it wasn't user space but some kernel routine that consults the

accelerometer and decides when to stop I/O, then we could indeed stop

querying the accelerometer while the disk is in standby mode and delay a

subsequent spin up for the time required to gather the necessary

accelerometer data. However, as I have explained before, it is not quite

trivial to implement all this in kernel space and I'd like to get head

unloading merged first.

Elias
